117909-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117909-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,0 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117909-45:
(8*1)+(7*1)+(6*7)+(5*9)+(4*0)+(3*9)+(2*4)+(1*5)=142
142 % 10 = 2
So 117909-45-2 is a valid CAS Registry Number.
